With the high penetration of distributed generation (DG) systems based on wind energy sources, it is necessary to develop technologies for improving the efficiency of system operation. Among the solutions proposed in the literature, the Electromagnetic Frequency Regulator (EFR) device has proven to be an attractive solution for improving the performance of the wind systems. This work proposes a dynamic modeling and control design for EFR applied to a wind systems. The system controllers parameters are designed by using root-locus method (RLM) in order to realize desired dynamic performance. Besides, a stability analysis for closed-loop system is assessed to obtain the operating limits. Finally, simulation results demonstrate the effectiveness of the proposed dynamic modeling and system controllers performance.
